Anil Khanna Citius, Altius, Fortius Faster, Higher, Stronger – the Olympic motto could just as easily be applied to the expectations driving the alarming rate of evolution of embedded hardware. In the form of today’s mobile devices, we now hold more processing power than high-end PCs of yesteryears! A single mobile device has replaced the functionality of a myriad of discrete devices: GPS, camera, pager, voice … Read More

Ricardo Anguiano Andrew Stubbs, an esteemed member of our Embedded Software Tools team, recently got a chance to show off his debugging and performance tuning skills on an innovative multi-process, multi-language, network distributed application. Andrew built a three element client-server software build system enhancement called cs that provides a build performance boosting cache feature while capturing usage data … Read More

Ricardo Anguiano Imagine this scenario: Your custom hardware design is still being worked out by your hardware team. Early stage, pre-silicon design models are running in simulation. The software team has started their work using this hardware simulation and they’ve got Linux running on the simulated target and they are now debugging kernel, driver and application code. The software team helps exercise the … Read More

Debugging with printf() or not ...

Posted by Colin Walls

Colin Walls My colleague Richard Vlamynck [who has been a guest blogger here] and I were discussing tracing and debugging. Like me, he has been doing software for a few years. Hence, when we considered tracing and instrumenting code, he commented “It used to be easy to see what effect trace statements had on your program because, as you put more or less trace cards in your Fortran deck, you could visually … Read More

Colin Walls I often tell people that my job is that of a “professional enthusiast”. I get enthusiastic about products/technologies, then infect other people with that enthusiasm. Well, that is the idea anyway. I enjoy doing this most of all when I get to stand up in front of an audience, as a direct connection with real live human beings is the best way to communicate. However, there are times when … Read More

Tracing Summit: hearing from the users

Posted by Hollis Blanchard

Hollis Blanchard I was in San Diego yesterday for the Tracing Summit, part of the Linux Plumbers’ Conference. Topics included SystemTap, ftrace, perf, and GDB tracepoints… and of course LTTng. Even better than putting developers from all those projects in the same room, in the morning there were a couple presentations from tracing users: Frank Rowand and Vinod Kutty who use tracing on embedded systems and … Read More
